i agree with others comments on this, i had a half bottle of this in the boot, went to use it during the cold snap and it was like a slush puppy, and this was undiluted, think it said on the bottle effective to -3c or round about that

yeah but screenwash is used as an additive in the washer bottle to prevent freezing off the window washers,as well as cleaning the windows. so it should work at below -5. when it was snowing up in scotland and probably everywhere else in the uk, the roads where terrible, car windows where getting dirty, but we had nothing to spray them with as the washers had frozen.:thinking:

Strange that people are having problems with this freezing as its screen wash not anti-freeze.
